Lumen OHM Assessment

Given the function below, determine if the function is continuous at the point `x=-3`. If not, indicate why.

`f(x) = (x^2-1)/(x+3)`

Continuous at `x = -3`
Not continuous: `f(-3)` is not defined; this is a removable discontinuity
Not continuous: `f(-3)` is not defined; this is not a removable discontinuity
Not continuous: `lim_(x rarr -3) f(x)` does not exist
Not continuous: `f(-3)` and limit exist, but are not equal
